Apache Kafka vs CData Sync

Apache Kafka is an open-source distributed event-streaming platform for data pipelines, streaming analytics, data integration, and mission-critical applications. Applications can publish and subscribe to event streams, retain them durably, and process them either in real time or later. Kafka supports durable, fault-tolerant replication across availability zones, data centers, or geographic regions. Kafka Streams provides stateful operations, aggregations, windowing, joins, event-time processing, and exactly-once processing. Kafka Connect links hundreds of event sources and sinks, including Postgres, JMS, Elasticsearch, and AWS S3. Deployments can use bare metal, virtual machines, or containers, on premises or in the cloud, with self-managed or vendor-managed options. The project describes network-limited throughput, latency as low as 2 ms, and clusters of up to 1,000 brokers. Kafka is self-hosted, free, and open source under Apache License 2.0. A local quickstart requires Java 17 or later.

CData Sync replicates data from databases, SaaS applications and APIs to databases, data lakes and data warehouses. CData says it supports over 250 sources and offers a catalog of cloud and on-premises destinations. Pipelines can use incremental loading and, for supported sources, real-time Change Data Capture. ETL and ELT transformations are available through SQL or dbt Core and Cloud. Users can schedule pipelines and receive email, Slack or Teams notifications when workflows finish or fail. Sync can run on premises, in cloud environments or through CData-hosted Sync Cloud, and is listed for Linux, Windows, web, API and self-hosted use. Its APIs and scripting can manage connections and jobs, inspect status and history, download logs, and run custom behavior around jobs. It can adjust destination schemas when source schemas change; its overview says it does not delete destination columns or reduce their size. CData documents TLS/SSL encryption and encrypted sensitive configuration values and reports third-party SOC 2 Type II and ISO/IEC 27001:2022 audits. A 14-day trial is available; there is no free plan.
